I believe the above is from 1937 not the 1920s. The license plate on the car shows a 937 and the vehicle is typical of a 1935-36 styling. I unsuccessfully tried to identify the vehicle.

Edit: the license plate is definitely 1937 followed by a crown. 1937 is the 1st time that crowns appeared on Ontario plates, positioned in the top left and right corners.
Edit:The car is a 1937 Chevrolet

A drawing of London, Ontario from around 1840. This looks towards the courthouse from the west bank of the Thames River, just upstream from the fork:

Think Toronto looked like a third world city in the 1800s? Welcome to downtown London, ca. 1880. I believe this is an early version of the Covent Garden market, with Dundas street in the background. All these buildings have likely since been demolished:

Fast-forward to the 1990s. Here's a shot of One London Place under construction in 1991:

And a shot of the downtown in 1996. The black building to the right is the old CN building, which doubled as the city's train station:

And that was imploded in early 2001, making London perhaps one of the few cities in this thread to actually create a larger gap in its skyline. Strange to think this was only a few months before 9/11.
